CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation in-part of U.S. Non-Provisional patent application Ser. No. 16/509,434 entitled, “INTEGRATED MULTI-VIEW SURVEILLANCE CAMERA SYSTEM FOR VEHICLES” filed Jul. 11, 2019.

TECHNICAL FIELD

The present disclosure is related to the field of image processing. More particularly, the present disclosure is related to methods and systems for providing surveillance in automobiles using image processing techniques.

BACKGROUND

When it comes to purchasing automobiles including passenger vehicles, features related to the safety and security of the driver as well as the passengers are considered as the most important requirements by most buyers. Safety features in vehicles have come a long way over the past several decades. Starting from increasing the sturdiness of the vehicle's structure, innovations such as seat belts, airbags, parking cameras, and the like, have improved passenger safety exponentially. Even though vehicles have become comparatively much safer over the years, the number of accidents and accident-related mortalities aren't coming down. This is mainly due to the fact that more and more individuals are buying vehicles thereby increasing the chances of accidents. Moreover, the performance of vehicles, as well as the quality of roads, have increased drastically thereby indirectly increasing the incidents of serious accidents due to incidents like rash driving, over-speeding, and the like.

Modern-day problems require modern-day solutions. Hence, there is a need to upgrade conventional vehicle accessories to meet the demand of modern-day driving and road conditions. Moreover, efficient use of advanced technological solutions may also be incorporated to improve safety in vehicles. In the present day, it is essential to equip vehicles with advanced electronic image sensor systems to be able to follow road markings and information signs, especially during heavy traffic congestion. Automotive camera modules comprising image sensors and various camera components intended for automotive use may be installed inside or on the front or rear side of a vehicle for increasing the safety of vehicles. Automotive cameras assist drivers in detecting blind spots and parking vehicles. These cameras are mainly intended to prevent collisions, record drivers' inclination, and altogether, offer an enhanced driving experience. Moreover, these cameras serve as high-performance security and surveillance systems for automobiles. Modern automobiles feature advanced camera modules based on several avant-garde technologies, such as 3D depth sensing, ultra HD display, and infrared thermal technology.

Automotive manufacturers are increasingly looking to incorporate state-of-the-art automotive imaging solutions, such as the Advanced Driver Assistance Systems (ADAS), into the vehicles for superior performance. Some of the other advanced automotive imaging solutions include Lane Departure Warning (LDW), Traffic Sign Recognition (TSR), Forward Collision Warning (FCW), Intelligent Headlight Control (IHC), Traffic Jam Assist (TJA), Automatic Emergency Braking (AEB), and Blind Spot Monitoring.

The global automotive camera module market is anticipated to witness exponential growth over the coming years. The key factors conducive to market growth include the surging demand for automotive safety solutions, the rising demand for luxury vehicles, the booming automotive industry, technological enhancements in automotive imaging solutions, the growing demand for autonomous vehicle safety features, and the increasing government initiatives towards the introduction of advanced vehicle safety solutions. The amplifying use of ADAS and other automotive imaging solutions in passenger vehicles due to governmental vehicle safety mandates is a key growth propeller for the global market. For instance, the European Union has reportedly mandated the use of ADAS, LDW, and AEB systems in passenger vehicles in a bid to prevent road mishaps.

Referring to the figures, FIG. 1 is a block diagram 100 of the architecture of a surveillance management system 102 connected to a plurality of client devices 130 via a network 128. As shown in FIG. 1 , the surveillance management system 102 may include processor(s) 104 and memory 106 that are communicatively coupled to each other. Further, the personnel evaluation system 102 may include a database (DB) 108 that may be communicatively connected to the memory 106. Furthermore, as shown in FIG. 1 , memory 106 may include a receiving module 110, an image processing module 112, a secondary data processing module 114, a machine learning module 116, an Artificial Intelligence (AI) module 118, an alert generation module 120, a communication management module-s 122, and an event management module-s 124. One or more client devices 130 may be communicatively connected to the surveillance management system 102.

Components of the surveillance management system 102 may be any combination of hardware and programming to implement the functionalities described herein. In some implementations, the programming may be processor 104 executable instructions stored on a non-transitory machine-readable storage medium (e.g., memory 106), and the hardware may include at least one processing resource to retrieve and/or execute those instructions. Processor(s) 104 may include, but are not limited to, one or more digital signal processors (DSPs), one or more microprocessor, one or more special-purpose computer chips, one or more field-programmable gate arrays (FPGAs), one or more application-specific integrated circuits (ASICs), one or more computer(s), various analog to digital converters, digital to analog converters, and/or other support circuits. Processor(s) 104 thus may also include the functionality to encode messages and/or data or information. Processor(s) 104 may include, among other things, a clock, an arithmetic logic unit (ALU), and logic gates configured to support the operation of processor(s) 104. Further, the processor(s) 104 may include functionality to execute one or more software programs, which may be stored in the memory 106 or otherwise accessible to processor(s) 104.

Memory 106, may store any number of pieces of information, and data, used by the system to implement the functions of the system. The memory 106 may include, for example, volatile memory and/or non-volatile memory. Examples of volatile memory may include but are not limited to volatile random-access memory (RAM). The non-volatile memory may additionally or alternatively comprise an electrically erasable programmable read-only memory (EEPROM), flash memory, hard drive, and the like. Some examples of volatile memory include, but are not limited to, dynamic RAM, static RAM, and the like. Some example of the non-volatile memory includes, but are not limited to, hard disks, magnetic tapes, optical disks, programmable read-only memory, erasable programmable read-only memory, electrically erasable programmable read-only memory, flash memory, and the like. Memory 106 may be configured to store information, data, applications, instructions, or the like for enabling the system to carry out various functions in accordance with various example embodiments. Additionally, or alternatively, the memory 106 may be configured to store instructions which when executed by processor(s) 104 cause the surveillance management system 102 to behave in a manner as described in various embodiments.

In one implementation, the network 128 may be a wireless network, a wired network, or a combination thereof. Network 128 may be implemented as one of the several types of networks, such as intranet, local area network (LAN), wide area network (WAN), the internet, and the like. Network 128 may either be a dedicated network or a shared network. The shared network represents an association of the several types of networks that use a variety of protocols, for example, Hypertext Transfer Protocol (HTTP), Transmission Control Protocol/Internet Protocol (TCP/IP), Wireless Application Protocol (WAP), and the like, to communicate with one another. Further, the network 128 may include a variety of network devices, including routers, bridges, servers, computing devices, storage devices, and the like.

During the operation, the receiving module 110 may receive data from the client devices 130. Data may include images captured by the cameras of the client device, audio captured by the microphone, data from the plurality of sensors, input provided by the user of the client device, and the like. The image processing module 112 may process the images received from the client device to generate useful information. Images received from the client device 130 may include images from the surroundings of the vehicle received from the first set of cameras and images from the cabin of the vehicle received from the second set of cameras. The image processing module processes these images in real-time and determines information including other vehicles travelling close to the primary vehicle on which the client device is disposed, details from the registration plate of the other vehicles, speed of the other vehicles, distance and trajectory of the other vehicles, signboards on the route that is being travelled by the vehicle, any stationary object detected on the route of the vehicle such as construction barriers, cones, diversion signs, speed breakers, etc., upcoming rest areas, upcoming traffic congestion, upcoming danger signs, and the like. In one example, the first and second set of cameras of the client device may have forward, sideward and backward facing cameras to capture information from the surroundings of the vehicle as well as from the interior of the cabin.

The secondary data processing module 114 processes audio, speed, location, and other related data received from the sensors of the client device to determine useful information. The received data are synchronized with the images received from the cameras to determine one or more events. The image processing module 112 and the secondary data processing module 114 work along with the machine learning module 116 and AI module 118 to identify useful information in real-time. While the machine learning module 116 may use existing models to process images for the identification of useful information, it also continues to learn from the data that is being gathered currently. Existing learning models may be adapted with the data received from the client device to further customize the learning model and improve the efficiency of the learning model. The AI module 118 works along with the machine learning module 116 to alert the user upon detecting primary events, secondary events, or adverse events. The alert generation module 120 and the event management module-s 124 may be responsible for determining the events and alerting the user regarding the same. The communication module-s 122 may be responsible for managing all the communication between the server and client devices.

Herein, events that are monitored by the surveillance management system 102 may be classified into primary events, secondary events, and adverse events. Primary events may include events pertinent to the surroundings of the vehicle. Examples of primary alert events include other vehicles travelling dangerously close to the primary vehicle and route information. When another vehicle travels dangerously close to the primary vehicle (the vehicle in which the client device 130 installed is referred to as the primary vehicle throughout this description), the surveillance management system 102 triggers a primary event and notifies the same to the user (the user may include driver or passenger of the primary vehicle). The surveillance management system 102 determines this by calculating the distance and trajectory of other vehicles approaching the primary vehicle. When a predefined speed/trajectory criterion is surpassed, the surveillance management system 102 alerts the user regarding the presence of such a vehicle. Furthermore, route information may also be provided to the user in real-time. Route information may also be considered as a primary event by the surveillance management system 102. Herein, route information may include at least one of: barriers detected on the route, stationary objects detected on the route, upcoming rest areas, upcoming exits, upcoming diversions, upcoming traffic, and the like.

The secondary event may include events such as lacking alertness of the driver, commotion inside the cabin, passengers not wearing seat belts, and the like. Herein, the alertness of the driver is determined by monitoring the eye movements and facial expressions of the driver from the images received. Based on the images received from the cabin, if the driver's eyes are closed for a predetermined amount of time or if the driver yawns or shows other signs related to sleepiness/tiredness, the event management module-s 124 triggers a secondary alert event. The server may send instructions such as warning signals, audio alerts, video alerts, and the like, to the display unit of the client device 130.

An adverse event may include events such as a breakdown of the vehicle, an accident, and the like. Herein, the surveillance management system 102, processes the captured images from the first and second set of cameras, the location information, and the speed information to determine the adverse event. Clues received from the primary alert events such as dangerously driving vehicles, objects and diversions on the road, driver alertness, and the like, are cross-checked upon determining the adverse event to determine possible reasons for the adverse event. If the vehicle comes to an abrupt halt or follows an unexpected trajectory all of a sudden, an adverse event may be predicted. Such events mostly follow after the primary and/or secondary alert event happens. In some cases, such events may happen even without triggering of primary/secondary alert event as well (such as vehicle breakdown). Upon determining an adverse event, the surveillance management system 102 transmits an emergency dataset to one or more emergency contacts. The emergency dataset may include images captured from the first and second set of cameras, location information during the time at which the adverse event occurred, registration information of other vehicles, and the like.

FIG. 2 is a block diagram 200 of the architecture of an in-vehicle surveillance device 202 communicatively connected to the surveillance management system 102. The in-vehicle surveillance device 202 corresponds to one of the client devices 130 of FIG. 1 . The in-vehicle surveillance device 202 may also comprise processor(s) 202 communicatively connected to a memory 206 and a database 208. Memory 208 may include a transmission module 210, a display management module 212, a camera management module 214, a sensor management module 216, an alert management module 218, a communication management module-c 220, an event management module-c 222, and a Graphical User Interface (GUI) management module 224.

During operation, the transmission module 210 may transmit images, sensor data, and other output generated by the in-vehicle surveillance device 202 to the surveillance management system 102. All communication to and from the device is managed by the communication management module-c 220. The display management module 212 manages the display unit of the in-vehicle surveillance device 202. The display unit may comprise a screen capable of displaying images and/or video feeds to the user. The GUI management module 224 may assist the user in providing inputs to the display unit. The camera management module 214 captures images from the surroundings of the vehicle and from the cabin of the vehicle using a first and second set of cameras and transmits them using the transmission module 210. The sensor management module 216 manages the plurality of sensors. The alert management module 218 sends alerts to the display unit while the event management module-c 222 triggers alert based the events determined and notified to the in-vehicle surveillance device 202.

FIG. 3 is an exemplary exploded view 300 of the in-vehicle surveillance device according to the embodiments of the present disclosure. The casing 302 of the in-vehicle surveillance device comprises of an integrated circuit board 304 onto which various components of the in-vehicle surveillance device may be disposed. Components may include cameras, sensors, and the like. The display unit 306 may be placed on top of the integrated circuit board 304 and may further provide one or more activation controls. Further, a rear-view mirror/touch-enabled screen 308 may be provided on the top of the display. When the display is turned off, screen 308 may act as a rear-view mirror.

FIG. 4 is an exemplary top plan view 400 of a vehicle equipped with the surveillance system described herein according to the embodiments of the present disclosure. As illustrated by the figure, the client device disposed inside the vehicle captures 360-degree views. The captured images are sent for real-time processing to receive useful information as described in the earlier sections of this document.

FIG. 5 is an exemplary view 500 of the integrated circuit board 304 disposed within the in-vehicle surveillance device according to the embodiments of the present disclosure. The integrated circuit board 304 may comprise one or more cameras (504A, 504B, 504C, etc.) on its front and rear sides.

FIG. 6 is an exemplary block diagram 600 illustrating the communication flow between various primary components of the vehicle surveillance system. Herein, the surveillance management system 102 operated from the server side is configured to communicate with one or more client devices and provide useful information as instructions to the in-vehicle communication device in real-time. The rear-view mirror/display device 604 may be used for communicating with the user in real-time via the server. Furthermore, client network 606 may comprise one or more similar client devices installed in other vehicles. The server may also be configured to allow vehicle-to-vehicle communication by allowing various client devices to connect to each other. In one example, two different vehicles fitted with client devices depicted in this disclosure may be allowed to communicate with each other via the server. The server may allow users of one such client device to communicate directly to the other using video/audio/text-based communication methods.

In one example, the in-vehicle surveillance system 202 may further comprise a microphone that captures audio feeds from the cabin of the primary vehicle. The surveillance management system 102 may allow one client device disposed in the primary vehicle to communicate with another client device disposed in a second vehicle. The surveillance management system 102 may further allow a user of one client device to communicate with a user of another client deice via audio calls, video calls, or text messages. In another example, the surveillance management system 102 may allow the client device to communicate with an electronic device such as a smartphone, a personal computer, a laptop, a tablet, and the like. Herein, the server may allow a user of the client device to communicate with the electronic device via audio calls, video calls, or text messages.

In one example, the surveillance management system 102 may combine location information and speed information of the primary vehicle with the images captured from the primary and secondary cameras and the audio captured from the microphone to determine the occurrence of adverse events. Further, emergency contacts who may be contacted upon determining adverse events include friends or family chosen by the vehicle owner, towing services, vehicle service centers, insurance companies, law enforcement agencies, emergency services closest to the location at which the adverse incident happened, and the like.

In one example, the cameras used in the client device are equipped with night vision capabilities and infrared sensors. The client device may replace the traditional rear-view mirror and may be designed to look and act as a rear-view mirror with additional functionalities as described by the present disclosure. The outer portion of the display unit may be equipped with a reflective element that acts as a mirror for viewing rearward field of view when the display is switched off.

In one example, the client device may further be provided with local storage for storing captured data apart from transmitting them to the server. The local storage may store data for a fixed period of time before overwriting the same. In scenarios such as loss of network connectivity, the data may be stored in the local storage and then transmitted to the server upon reestablishing the connection.

In one example, the surveillance management system 102 may scan the registration plate of other vehicles that travel near the primary vehicle to determine publically available data related to the registration number of the other vehicle such as the make of the other vehicle, model of the other vehicle, the registration date of the other vehicle, insurance details of the other vehicle, owner information of the other vehicle, and the like. In case of an adverse incident, this data may be used to determine/track vehicles that were travelling nearby.

In one example, the server may provide an automated response mechanism for determining primary, secondary, or adverse events. An automated communication may be initiated by the server to allow users to provide their queries or requirements immediately via the touch-enabled display unit of the in-vehicle surveillance device. Upon determining an event, the server may either allow a dedicated executive to communicate manually with the driver/passenger of the vehicle via text/video/audio-based communication means via the display unit. Herein, a dedicated individual may communicate directly with the driver/passenger to identify their present status and requirements. Images and other related data may be retrieved by the executive to identify the present circumstances to provide appropriate service. Alternatively, this process may also be automated. Herein, an intelligent communication system backed by the AI module may establish communication with the driver/passenger to receive requirements. The system may fulfill the requirements automatically or transfer them to the dedicated executive depending upon the type of request received.

In one example, the server may allow the client device to communicate with an electronic device such as a smartphone, a personal computer, a laptop, or a tablet. Herein, the server may allow a user of the client device to communicate with the electronic device via audio calls, video calls or text messages. Herein, passengers may be able to communicate directly with individuals using any electronic device via the display unit, the cameras, and the microphone of the client device. Similarly, communication may also be possible from one client device to another client device disposed in another vehicle. The server may be able to connect multiple client devices in the client device network to facilitate communication among multiple vehicle owners who have vehicles fitted with the proposed client device.

One of the key advantage of the proposed solution compared to existing solutions is that the client device used herein is disposed inside the vehicle as a single unit with cameras and sensors attached to it. The advantage of such a device is that the cameras and sensors are not prone to external conditions such as heat, rain, snow, dust, and the like. The secure positioning of the client device makes it less vulnerable to wear and tear as well. Cameras and sensors placed externally to capture the surroundings may be damaged easily due to external factors as mentioned above. The proposed client device overcomes these problems by providing a safer and robust alternative.

Moreover, repair and upgradation of the client device may be comparatively easier since most of the components are disposed within the device at a single location which is easily accessible. While conventional solutions provide multiple sensors and cameras placed around the vehicle's body, it may be costly and time consuming to diagnose problems. Technicians may further have to work on different parts of the vehicle to remove/replace faulty components thereby causing a lot of hardships to the technicians as well as to the vehicle owner. The solution presented herein avoids such complications and provides a client device that comprises all the primary components in one place.

It may be noted that the above-described examples of the present solution are for the purpose of illustration only. Although the solution has been described in conjunction with a specific embodiment thereof, numerous modifications may be possible without materially departing from the teachings and advantages of the subject matter described herein. Other substitutions, modifications, and changes may be made without departing from the spirit of the present solution. All the features disclosed in this specification (including any accompanying claims, abstract, and drawings), and all of the steps of any method or process so disclosed, may be combined in any combination, except combinations where at least some of such features or steps are mutually exclusive.
